Abstract
We present the first science for the Astrophysical Virtual Observatory (AVO) project. The exploitation of astronomical data beyond classical identification limits with interoperable tools for statistical identification of sources is now a reality. We show how the AVO prototype has been used to identify high redshift type 2 AGN in the two GOODS fields. Using an empirical estimator for the X-ray luminosity, we find many high power candidates which qualify as active galactic nuclei (AGN). Thirty-one of these sources have high estimated powers (> 1044 erg/s) and therefore qualify as optically obscured quasars, the so-called QSO 2. This significantly increases the number of such known objects in the GOODS fields, and provides new estimates for the QSO-2 number density. This work shows how the first Virtual Observatory interoperability gains are leading to scientific discovery.
